About this 7.18ct lab-grown marquise diamond

This 7.18ct lab-grown marquise sits in the over five carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included) and certified by IGI LG644481679 or 644481679. Listed at 3 retailers as of October 30, 2026, with prices from $8,347 to $10,017, a $1,669 spread on the same certified stone. Kay Jewelers lists it at $10,017. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
